I am a Dunham Jackson Assistant Professor in School of Mathematics in University of Minnesota.
I got a Sc.D. in mathematics at MIT. My thesis advisor was George Lusztig.
Currently I am interested in geometric and combinatorial representation theory.
I have a cat whose name is "Yaong-ee" which means "Meowy".

This semester I teach MATH 1271 (Calculus I).
